WILLIAM HUNTING, OF BROOKLINE, MASSACHUSETTS.

LAVATOR-Y renames;

Be it known that I, WILLIAM .BUNTING, a citizen of theUnited States, residing atv Brookline,; in the county of Norfolk and.

.State of Massachusetts, have invented an Improvement in Lavatory A paratus, of which the followingis a speci cation.

This-invention relates tocertain improvements in. lavatory apparatus, and particularly that especially designed for use in convantageous when used in other relations.

v The use ofliquid soap in surgical lava' I tories is particularly desirable, but the ref "cure. a portion-of the contents thereof, which ceptacle in iwhich it is ,usually contained must be touched. by the hand,- in order to separticularly objectionable feature in this relation.

desired quantity of liqnidsoap may bedisv ing the hands or arms to the apparatus, and

accordingqtoiny invention. Fig. 2 is a sectional view taken 'at the line 2 2.of Fig. 3.

4 is a sectional view taken at the line 44 of the soap pump.

In the drawing a indicates an ordinary 'setbasin-having the usual horizontally pro jecting rim or. slab, said basln being sup- .mounted-at their rear'ends on the wall d, in' 'the-rear of the basin, and extending ported upon a 7 pair of horizontally disposed, tubular brackets," b, c, said bracketsbeingy therefrom beneath the rim in parallelism at opposite sides of the bowl, adjusting screws being provided between the upper sides of dicularly thereto.

, The object of my invention is .to provide 'a. lavatory basin with means whereby any I 25 charged at a convenient point without touch front of the bowl.

- the brackets and the under side of the basin rim. r

Said'bracketsb, c, vided at their front ends with rightangularly. shaped, oppositely disposed lugs e, e, and bell-crank levers f, f are pivotally mounted on theen'ds of said of each lever extending forwardly beyond the front edge of'the' basin rim, or front outline thereof, and approximately perpen- Said levers are arranged to swing horizontally away from each other and are connected to, operating rods 9, 'whichare' reciprocally mounted Within 9, the brackets b, '0, so that as said levers are pushed laterally .outward from the middle of the bowl, said rods will be pushed inwardly, or rearwardly.

The forwardly projecting arms of said levers f, are provided with vertically arrange flattened end i portions, which "are held" at such a height-that the user may conveniently press the ,hip' or the side of the leg betweenIthe-knee and the hip, against elther' lever as he stands'between them in I Bell-crank levers, '73, mounted on lugs Z370 secured to the brackets-b, 0, in therear of the wall (1, one arm of each lever being held in engagement with its corresponding rod 9 or g, as shown in Fig.

4. The lever 11 is connected, by a link 7', to

- one arm of a bell-crank lever Z, mounted on on a pump 'cylin-' a bracket m, supported der I 'A closed receptacle 0,-for'liquid soap, is connected by a pipe'o to the cylinder 12, pipe beingsupported by a suitable bracket 39 on the rear side of the wall, which also providesa support for the pump cylinder and the receptacle 0.

A plunger n' is mounted in the cylinder n and is held in operative engagement'with the opposite arm of the bell-crank lever Z to I that which is connected to thelink j, so that,

when said. lever Z is swung, said plunger may be reciprocated, and by providing an adjustable connection between the lever Z and link 7" the length of the stroke of the piston'may be yaried.

Arjspring h is'provided in the cylinder n which is arranged to engage the plunger n to return the parts to initial position.

Check valves g, vided; in the pipe lugs, an arm g are respectively pro-- 0" and a discharge pipe 0 are respectively proi, are respectively n which leads from the pump cylinder, so that, as said plunger 11. is reciprocated, the liquid may be drawn from the receptacle 0 and discharged through the pipe n;

The bell-crank lever 71' is connected to a link 1', which is' in turn connected to the operating-lever s, of a water supply valve t, of the self-closing type. I

A discharge pipe u 15 mounted in the wall 03, within a casing :10 and is connected at its rear end to the discharge port of the water supply valve t, by a pipe t, and at its front end to a depending spray nozzle y, which is held over the middle of the basin, so that, when the valve t is opened, water will be discharged from the nozzle, the latter being held in such a position that the hands may be conveniently held thereunder.

The discharge pipe 11. from the pump a, is connected to a pipe '0 which extends through a packed joint and coupling into pipe at. and through said pipe u and the nozzle 3 and terminates at itsouter end a short distance beyond the end thereof, said nozzle being preferably provided with a spray strainer z in its end in the middle'of which the pipe 1) is supported. The pipe '0 is of small diameter and has a depending end portion corresponding to the depending nozzle y, so that, when said pipe is filled with liquid, air cannot pass'the liquid therein, which will be retained by air pressure.

lVith the above described apparatus, when the lever f is pushed outwardly, the pump plunger will be raised, so as to force a supply of soap into the discharge pipe n, and after this operation has been repeated a number of times, the pipes connected to the pipe 11. will become completely filled with the liquid soap, so that each time the lever f is operated a measured quantity of liquid soap will be discharged from the pipe 12. As the receptacle 0 is arranged below the level of the discharge end of pipe v, there will be no leakage of the soap from the receptacle through the pipe, and soap will only be discharged when the pump is operated. The user will, ordinarily, hold his hands beneath the discharge pipe and first operate the lever f to discharge a supply of soap onto his hands, and then will push against the lever-f and open the supply valve, so that then Water will be discharged onto his hands from the nozzle.

The particular form of valve t which is used is notmaterial, that is, either a single valve controlling a single water supply may be employed, or a compound valve controlling both a hot and cold water supply may be provided, the type which I preferably employ being one which will first turn on the cold water and then gradually turn on the hot water and shut ofi the cold Water, as the lever is pushed in one direction.

It will be apparent'that, with the above described apparatus, the user may wash his hands with soap and water without touching any apparatus and at the same time may also have free use of his hands and arms.

It will also be apparent that, with the above'described apparatus, all the apparatus is concealed except that which must necessarily be exposed, namely, the operatinglevers and the single discharge pipe for the water and soap, so that, the whole device will have an attractive and ornamental appearance and a minimum amount of surface will be exposed which must be kept clean.
